Abstract:
We report a case of bilateral multidirectional instability of the scaphotrapeziotrapezoid joint associated with osteoarthritis of the same joint and static dorsal intercalated segment instability. Because there is no previous trauma it is likely that this is a case of nontraumatic instability at the scaphotrapeziotrapezoid joint causing a dorsal intercalated segment instability deformity of carpal malalignment and secondary scaphotrapeziotrapezoid osteoarthritis.
